Identifying the DHCP server IP....

Hi Group,

I have enabled automatic DHCP in my machine. I am assigned by an IP by
the DHCP server . Is there any way by which i know the IP address of
the DHCP server which assigned the address ?.
Pls advice me.

Yes, look when your machine boots, you should see something like
'DHCP received from ....' with the IP of the server.
Besides, why you want to know ?

Hi David,

Thanks for the response. But my kernel output messages will be
suppressed, so is there in any file the DHCP server IP will be
recorded. I have a scenario where i want to download a file thro' tftp
automatically when i press a key...my TFTP server and DHCP server are
one and the same. So if i could identify my DHCP server IP i could read
that and will give that as argument to my TFTP client to download.
Any Suggestions.

Have a look at

/var/log/daemon.log

Thanks all. I ran the dhcpclient-script and grepped the output for
DHCPOFFER and stored the IP. Thanks alot for u'r valuable inputs.

Ifconfig will usually tell you.

He didn't asked for the ip address he received, he wanted the
IP address of the dhcp server...

As I mentioned, ifconfig will tell you. You can also see what your dhcp
client provides. For example in SuSE 9.1, you'll find a file, such as
/var/lib/dhcpcd/dhcpcd-eth0.info, which contains the assigned address.

If your dhcp client program is 'dhclient', look at the files
/var/lib/dhcp/dhclient* .
